winset(usr, "default.button2", "image-file=")
Problem description:
I'm making a button on the skin that you drag stuff on to, and then it changes the Command of the button as well as the background (so you can tell which one it is). I'm just not really sure how to do so...
What goes after "image-file=______"
I am not very sure about the '(single quotes) but I think you should use it if your Filname.png has a space in between.
